Long-lived stimulated echo in a superconducting YBa2Cu3Ox powder
Drobinin A. V., Tsipenyuk Yu. M.
A two-pulse echo and a stimulated echo have been observed in a superconducting YBa2 Cu3 Ox powder in a static magnetic field. A stimulated echo has been detected an hour after the removal of exciting pulses (the memory effect). The field and temperature dependences of the echo amplitude are presented.
